Can I use a 4x4 axle actuator from my 1999 expedition on my 2005 expedition?

I'm having trouble with my 4x4 on my 2005 expedition the 4x4 low and high lights flash on the dash. to make a long story short the dealership I bought it from replaced a sensor but it's still not working and I contestant generality the idiots the dealership anymore. my brother thinks it might be the 4x4 axle actuator. I have an old 99 expedition so if I can use the actuator from that expedition I'd love to save the money on buying a new one but my brother isn't sure if I can. just looking for some help!

SOURCE: Stuck in 4 wheel drive high

I disconnected the electronic control on the transfer case and it seems to have unlocked the 4x4

At the back of the transfer case, near the top, there is a connector. I unplugged it and that seems to have disconnected the 4x4. My 2002 Explorer was stuck in 4x4, even though the 4x4 light was not on and I hit the Auto button a lot.

SOURCE: my 2006 ford f150 4x4 works fine in high and low

the 4x4 high light has been on far longer than the low ratio light, I suspect it has simply worn out and blown, try a new light. other than that the switch in the transmission could be faulty / have corroded connectors

SOURCE: 2005 Ford Expedition (4wd) with trouble codes p2104 and p2112

Shown here is the P2104 obd2 code and their general meaning. For a brief description of any particular OBD2 code and how to fix the obd2 trouble code, please browsw below. P2104 Engine TP Actuator Cntl System
This obd2 code is very common on newer vehicles which contain new design of throttle positioner sensor. Instead of putting a tps sensor at the side of your throttle body as in older engines, a throttle actuator control system is installed which eliminates the mechanical linkage (cable) between the throttle body and the throttle pedal. Under the throttle pedal, a throttle switch is installed and a throttle module or actuator is incorporated beside the throttle body. Because there is no mechanical device that wears out, it is more effecient in delivering better mileage and performance torque (besides...the actuator module performs better in getting all throttle signals to the ecm and trany).
To test this code, check the integrity of the wires going to both the throttle body actuator and the ecm including the throttle switch. Most of the time, if you have symptoms like trany going to a limp mode, the culprit originates from the trany circuit. However, if the symptom is engine related like hesitation, the problem resides in the throttle actuator itself which may sometimes includes the replacement of the whole throttle body assembly. Contact ATS if you need a wiring diagram or detailed fixes for your throttle actuator control system.
TIP:
Before replacing the throttle control actuator and throttle body, try cleaning the throttle plates and all plug-in wiring connections. Also, watch out the throttle body mounting bolts which can easily break (use care) when removing them.

SOURCE: 4x4 lights flash, will not engage into 4wd

This is called the selector motor and you may be correct this is a common problem with these trucks the selector motor goes bad and will not engage the correct gear setting you select.

4wd light flashing


When the light flashes it's generally a sign that it's not fully engaged hi or low and or stuck partially in either position. I would say it's the force motor that physically moves the linkages in and out of position is going bad. It should be able to be scanned by a tech and give you a code.

I've replaced upper ball joint both, cv axles both. And my expedition still clunks and jerks when I turn corners. Why?


We can't guess for you

The bottom ball joints usually go on those vehicles

Can't the shop that did the work tell you why?

Your not replacing worn parts obviously

Any experienced person to road test & inspect
under it, can resolve that problem

I have a 93 gmc sierra 1500 4x4 every time i engage it into 4x4 it blows the 4x4 fuse


Try unplugging the front axle actuator (at the front differential). If the fuse stops blowing, you have a short inside the actuator.

Where are the fuses for the 4x4 located on a 05 envoy


This not a fuse problem. When you switch to A4WD or 4HI, do the indicator light for those positions stay on solid or do they blink and then return to 2HI position? If so, then there is probably a problem with the transfer case actuator/motor.

2005 trail blazer very jerky and rough in 4x4 auto /hi sems to pull to one side then the other in a wandering motion had axles actuator checked seems to be ok what can cause this


If you're driving on dry pavement in 4x4 mode, you will get this pulling sensation. 4x4 should only be used when road conditions are wet or slippery. Another thing to check is when was the last time the transfer case fluid has been changed, it is required to be changed every 50K miles.

Using the 4x4


Was the 'hot smell' inside or outside the expedition? Was engine temp in normal range?
I would check transfer case and front axle levels and transmission also, to make sure everything is at proper level, as these items are often not checked at all, or not often.

1996 Yukon 4X4 Electronic Shift on Fly.


I had the same problem with the shift on the fly push-button 4x4 on my 97 Suburban. GM Shop manual indicates that it could be due to an encoder error on the actuator motor. Try pulling the transfer case fuse to reset the transfer case control module. Wait at least one minute. Re-install fuse then re-try operation. Did it last week and that saved me a trip to the dealership and extensive troubleshooting.
